The UPS technical glossary

May , 23 2023

This ups technical glossary is designed to help you to understand the technical terms used within the uninterruptible power supply (UPS) industry. A AC ripple Is the residual periodic variation of the DC voltage withina UPS which has been derived from an unwelcome alternating (AC) source. An AC ripple causes internal heating and deterioration of the UPS battery poles and so should be prevented fom...

Why Choose a Lithium-Ion UPS Battery?

Jun , 21 2023

Although lithium-ion UPS systems have been around for decades, most people have been hesitant to choose this option because they were more expensive. With the onset of advanced battery technology, lithium-ion UPS systems have become much more attractive due to reduced pricing that rivals most standard, lead-acid battery UPS systems. UPS systems feature a state-of-the-art lithium iron phosphate (Li...

Basic knowledge of filters

Jun , 21 2023

The Line filter is a filter circuit composed of capacitance, inductance and resistance. A filter can effectively filter out a specific frequency point in the power line or frequencies outside of that frequency point, obtaining a specific frequency power signal or eliminating a specific frequency power signal. A filter, as the name suggests, is a device that filters waves. Wave "is a very broad phy...

Lithium battery capacity loss cause analysis

Jun , 21 2023

Lithium-ion batteries are the fastest-developing secondary batteries after cadmium-nickel and nickel-hydrogen batteries. Its high-energy properties make its future look bright. However, lithium-ion batteries are not perfect, and their biggest problem is the stability of their charge-discharge cycle. This paper summarizes and analyzes the possible causes of capacity attenuation of Li-ion batteries,...

What are the characteristics of industrial UPS power supply

Aug , 29 2023

Industrial UPS power supplies need to focus on the ability to operate in high-temperature environments. The design of components must adapt to the operational requirements of the industrial environment, adapt to high temperature and humidity, and also be able to cope with the corrosion of corrosive gases on the system. Under various operating conditions and continuous full load operation, industri...

Why only online UPS topology provides mission critical load protection

Sep , 09 2023

Why does only online UPS topology provides mission critical load protection? Modern, static UPS systems are broadly classified into three design architectures: on-line, off-line and line interactive. This post describes and compares the three types and explains why – for truly critical loads – online ups topology is the only acceptable approach. Facility executives today face increased demands for...

Interface level standards between digital systems

Sep , 09 2023

Preface When we constrain the FPGA project, we often see such level standards, such as LVCOM18, LVCOS25, LVDS, LVDS25, etc. In fact, these are a series of level standards, in order to have a deeper understanding of the level standards, the following excerpts from the book "The FPGA Way" for the explanation of the level standards to understand. Dual Threshold Standard The so-called dual-threshold s...

What is the difference between single phase and three phase UPS?

Oct , 16 2023

When purchasing UPS for your business or organization, many factors should be taken into consideration, among which the choice of power supply between single phase UPS and three phase UPS is the foremost one. Though both of the UPS offer consistent backup power for dealing with unexpected situations, they have different roles. Here is a brief introduction of single phase vs three phase for those w...

How to calculate the required ups load capacity?

Oct , 19 2023

Measured in “watts”, UPS load capacity is an important factor to consider when choosing a UPS (uninterruptible power supply). It determines how many electronic devices the UPS system can support. This post will tell you how to choose the right UPS with required UPS load capacity in the following four steps. Clarify UPS Measurement Units UPS systems are rated either in kilowatts (kW) or in kilo-vol...

Ground Design

Nov , 10 2023

1、Introduction In the process of circuit design, grounding is a commonplace issue. The grounding method needs to be based on specific usage scenarios, and there is no universal grounding method. In this article, we will explain the essence of grounding issues, which is worth savoring carefully. 2、Classification of grounding The same hardware circuit may also have differences in grounding methods i...

Working principle of lead-acid battery

Dec , 23 2023

1. The generation of electromotive force of lead-acid batteries After the lead-acid battery is charged, the positive plate lead dioxide (PbO2), under the action of water molecules in the sulfuric acid solution, a small amount of lead dioxide and water produce dissociable unstable substances - lead hydroxide (Pb (OH) 4), hydroxide ions in the solution, lead ions (Pb4) remain on the positive plate, ...
